Terrific! I almost never look in any app's Advanced Preferences, since they're usually too esoteric for my needs. But yours has not only "can drag selection", but also "swap horiz & vert scroll wheel," which is extremely handy. (I've been missing v1.x's clickable arrows at the left and right ends of the bottom-of-window slider, but using the scroll wheel is much better.)

Now I have to decide which is more valuable for me: zoom using scroll wheel, or swap horiz & vert. I love both options.
